Bunker Mathew B

Bunker Mathew B, senior corporate VP of operations at Microchip Technology (MCHP), has filed 86 Form 4 transactions, all in that single company. The pattern is one-sided: zero open-market purchases and $1.8 million in open-market sales. The only recent sale came on May 13, 2026, when he disposed of shares worth $1,024,155.48. That single transaction accounts for more than half of his total sell value across the filing history. The rest of his activity is mechanical. On May 15 and August 15, 2026, he exercised options and had shares withheld to cover taxes, a routine pairing of M and F codes. The option exercises on August 15 totaled roughly $330,000 in value, with corresponding tax withholdings of about $92,000. Similar but smaller pairings occurred in May. He also received grants with zero dollar value on May 8, July 1, and August 7, 2026, which are compensation awards rather than purchases. The data shows no conviction buying. His acquired value of $35,465.40 comes entirely from option exercises and grants, not open-market acquisitions. The selling bias is clear: one large open-market sale in May, no purchases at any point, and the remainder of his filings driven by automatic compensation mechanics. The direction of his disclosed activity is consistently toward reducing his direct ownership stake in MCHP.
